#5: What makes a great conversation?

You might think the subject makes a great conversation, but according to Massey lecturer Ian Williams, it's more than that. It's full of layers and you never really know where it’ll end up — how it will change you by the time it ends. Williams explores the art of good conversation in the final episode of his Massey Lectures. *The 2024 CBC Massey Lectures originally aired in November.

How to develop 'in the zone' hyper focus

You've likely experienced it: that state of being in the groove, on a roll, lost in the process. It's what researchers call 'flow': a state intimately familiar to athletes and artists — or anyone who's been fully absorbed in a given task to the point where time seems to stand still. In this state there's a sense of self disappearing, presenting a paradox between a state in which you lose yourself, yet become yourself. Writer and triathlete, Suzanne Zelazo, delves into the mystery at the heart of flow in this documentary. *This episode originally aired on June 25, 2021.

Why spirituality is central to Indigenous mathematics

Indigenous math isn't just about numbers and equations, it involves culture, spirituality and more. Math professor Edward Doolittle, a Mohawk from Six Nations in Ontario, sees math as something embedded in Creation itself. In his Hagey Lecture at the University of Waterloo, he describes Indigenous mathematics as being grounded in cognition, emotion, the physical world and community. Indigenizing math, Doolittle hopes, will make it more approachable and meaningful to Indigenous students — show them how entwined it is with everyday life and something much bigger than ourselves.

How a natural catastrophe 8,000 years ago may have fueled Brexit

For the first two billion years, the Earth didn't have oxygen. That's just one of the many fascinating details Peter Frankopan reveals in his book, Earth Transformed: An Untold History. The Oxford professor of global history takes us on a multi-million year tour, illustrating the breathtaking ways climate has shaped the Earth and human civilization. How the collapse of a sediment shelf 8,000 years ago isolated what's now Britain from Europe, and its potential influence on the Brexit vote in 2016. Or how climate fluctuations correlate to periods of antisemitic violence. There's a lot to learn in this podcast. Have a listen.

Can empathy be dangerous?

It depends on who you ask. Until recently empathy was generally considered a positive thing. But a growing number of mostly conservative voices believe empathy can be extremely dangerous — even toxic. Their argument is that empathy can drive irrational thinking and behaviour in public life. The result is a growing battle over empathy in a world that has never seemed to need it more. If you like this podcast, you may want to listen to this: Why practicing empathy is far from simple. Guests in this podcast: Matt Richins – neuroscientist and psychologist, who did research on empathy at Exeter University, UK. Susan Lanzoni – author, historian of psychology, psychiatry, and neuroscience and professor at Harvard’s School of Continuing Education Mary Gordon – founder of Roots of Empathy program, Toronto Michael Slote – author, philosopher and professor of ethics at the University of Miami Margaret Davidson – Roots of Empathy classroom facilitator, Chiganois Elementary Kourtney Simms – Chiganois Elementary teacher Ellie – Grade 1 student, Chiganois Elementary

The real reasons why more young women freeze their eggs

Egg freezing is one of today’s fastest-growing reproductive technologies. It's seen as a kind of 'fertility insurance' for the future, but that doesn’t address today’s deeper feelings of uncertainty around parenthood, heterosexual relationships, and the reproductive path forward. In this documentary, freelance producer Alison Motluk explores the history, significance, and reality of egg freezing for women.
